Optimal Pore Size of Honeycomb Polylactic Acid Films for In Vitro Cartilage Formation by Synovial Mesenchymal Stem Cells
Figure 4
Early phase of cartilage formation by synovial MSCs on PLA films. (a) Time lapse pictures. MSCs ( in 500 μL medium) were plated, cultured in chondrogenic induction medium, and then continuously observed. (b) Relative change in cell sheet area. Means and standard deviations are shown (). . values were determined by the two-way ANOVA with Tukey’s multiple comparisons test.
